Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Feasibility, acceptability, and preliminary efficacy of combined transcranial direct current stimulation and mindfulness for pain after total knee arthroplasty

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The project is to assess the preliminary feasibility, acceptability, and efficacy of self-administered preoperative tDCS+MBI in older adults (50+) undergoing TKR. And to determine the effects of 5, 20-minute preoperative self-administered tDCS sessions combined with brief MBI on analgesic medication consumption following TKR.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

preoperative active tDCS+MBI

Active tDCS with simultaneous meditation intervention will be applied.

Group Type EXPERIMENTAL

active tDCS paired with active MBM

Intervention Type DEVICE

Active tDCS with a constant current intensity of 2 milli ampere( mA)will be applied for 20 minutes per session for 5 times via the Soterix 1x1 tDCS mini-CT Stimulator device with headgear and saline-soaked surface sponge electrodes. The meditation intervention will be applied simultaneously with tDCS for 20 minutes per session for 5 times by a recorded meditation.

preoperative sham tDCS+MBI

Sham tDCS with simultaneous sham MBM intervention will be delivered.

Group Type SHAM_COMPARATOR

sham tDCS paired with sham MBM

Intervention Type DEVICE

For sham stimulation, the electrodes will be placed in the same positions as for active stimulation, but the stimulator will only deliver 2 mA current for 30 seconds. The sham MBM intervention will be delivered via a CD player that will look identical in both active and sham MBM.
